Sound recording Using java

I need to develop a java application to record phone calls and saves it as file in harddisc . Its usual LandPhone not a cell phone....
How can it be done...

1My Phone will be in Speaker Mode on

I am having following doubts

. My PC wont be having a microphone to take voice input... ........ what I plans is to have a connection to the COM port from Phone ..like the connections made for accessing internet..
but here i dont have intermediate modem between the two... so that plan of connecting a telphone out to a PC is stupidity i believe. I want to have another option..for recording.

Another easy way that i thought was to connect a microphone and use the XPs voice recorder for recording......Ut i though it would be googd to develop a smal java application for this

But the iam struck at follwoing areas

1. How i will i take voice as input to PC.

2. How my PCwii read it and convert to a file

If any have a better idea please help me....

Too difficult a question for "beginning Java". Moving thread.

Have also changed all text to black because some people find coloured text hard to read.

its have been 6 days .Yet i am not getting a reply.Please change this to a better forum matching the subject or else please any help me...
